Application filed September 14, 1914.. Serial No. 861,593.

To all whom it may concern:

Be it known that 1, JOHN PAULAUsKI, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ships, of which the following is a specification.

This invention relates to boats having water-tight compartments, and its object is to provide a novel and improved structure whereby a water-tight compartment is produced which extends throughout the entire length of the boat on both sides thereof.

The invention also has for its object to provide a novel and improved fender for preventing injury to the hull of the boat from collision, grounding and other causes.

The herein stated objects are attained by means of a combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of the boat, and Fig. 2 is an enlarged cross-section on the line 2-2 of Fig. 1.

Referring specifically to the drawing, the boat is provided with a double hull, the inner hull being shown at 10 and the outer hull at 11. The two hulls are spaced throughout their entire length along the sides of the boat and also at the bow and the stern, to form a water-tight compartment. The hulls taper toward the bottom as the hull of an ordinary boat, and the pointed bottom of the inner hull seats in the angle made by the pointed bottom of the outer hull, as shown in Fig. 2. The outer hull 11 has a continuous internal horizontal flange 12 near the top on which seats a continuous outstanding horizontal flange 13 at the top of the inner hull 10. These two flanges are clamped together by means of strong coiled springs 14. On top of the flange 13 is mounted a sheet 15 of water-proof fabric on which the springs 14 bear. The part of the hull 11 which extends above the flanges carries abutments 16 between which latter and the sheet 15 the springs are located. The abutments have threaded stems 17 whereby they are mounted on the hull 11, and they also carry bolts 18 for centering the springs. The sheet 15 also fits the inner surface of that part of the hull 11 which is above the flanges, and it serves to make a water and air-tight joint between the two hulls, at the flanges. In the event of a strain tending to distort the flanges, the sheet 15 will still hold the compartment air and water-tight. Between the hulls 10 and 11 are mounted coiled springs 19 for cushioning shocks from a collision or other causes. The upper portion of the hull 11 is also equipped with a tender for preventing injury from collision, grounding or other causes. This fender is composed of a belt which extends along the sides of the hull and around the stern thereof, and terminating close to the bow. The fender belt is composed of inner and outer sections 20 and 21, respectively, which are channel-shaped in cross-section and are telescopically connected. The inner section is secured to the hull 11 by bolts 22 or other suitable fasten ing means, and between said section and the outer sections are mounted coiled springs 23 which are compressed when the outer section is struck or strikes an obstruction and is forced inward, thus absorbing the shock and preventing damage to the hull. Separation of the sections is prevented by making the springs fast thereto.

On the inside of the hull 11 are threaded nipples 24: to receive caps 2%, said nipples being located to receive the inner ends of the bolts 22, and the caps inclosing the nuts 25 screwed on said ends 01": the bolts for holding the same. The caps prevent water from entering the space between the hulls 10 and 11 if any of the bolts 22 should ge loose or broken.

To guard the boat against a head-on collision a bow fender is provided, the same comprising two transversely arranged telescoping members 26 and 27, respectively, between which are mounted coiled springs 28. This fender operates in the same manner as the one first described.

I claim:

1. A ship comprising spaced inner and outer hulls, the outer hull having a continuous internal horizontal flange and the inner hull having a corresponding outstanding flange seating on said first-mentioned flange, and means for clamping the flanges together.

2. A. ship comprising spaced inner and outer hulls, the outer hull having a continuous internal horizontal flange and the inner hull having a corresponding outstanding flange seating on said first-mentioned flange, abutments on the outer hull, and springs between said abutments and the secondmentioned flange for clamping the same against the first-mentioned flange.

3. A ship comprising spaced inner and outer hulls, the outer hull having a continuous internal horizontal flange and the inner hull having a corresponding outstanding flange seating on said first-mentioned flange,

means for clamping the flanges together,

and a sealing means covering the joint between the flanges.

4. A ship "comprising spaced inner and outer hulls, the outer hull having a continuour internal horizontal flange and the inner hull having a corresponding outstanding tween said abutments and the second-nientioned flange for clamping the same against the first-mentioned flange, and a sealing material on the second-mentioned flange en? gageable by the springs, said material covering thejoint between the flanges.

In testimony whereof I aflix my signature in presence of two witnesses.
